a rhombus has an area of 60 square centimeters. if the length of one diagonal is 12 cm, find the length of the other

AlekseyPX

Answer:

10 cm

Step-by-step explanation:

The area (A) of a rhombus is calculated as

A = $\frac{1}{2}$ × d₁ × d₂ ( d₁ and d₂ are the diagonals )

Here A = 60, d₁ = 12, thus

60 = 0.5 × 12 × d₂ = 6 d₂ ( divide both sides by 6 )

d₂ = 10

The other diagonal is 10 cm

What is the solution to the system of equations below?

Karolina [17]

Answer:

The solution is the point (18,0)

Step-by-step explanation:

we have

$y=-\frac{1}{3}x+6$ -----> equation A

$y=\frac{1}{3}x-6$ -----> equation B

Solve the system by substitution

substitute equation B in equation A

$\frac{1}{3}x-6=-\frac{1}{3}x+6$

solve for x

Adds (1/3)x both sides

$\frac{1}{3}x-6+\frac{1}{3}x=6$

$\frac{2}{3}x-6=6$

Adds 6 both sides

$\frac{2}{3}x=6+6$

$\frac{2}{3}x=12$

$x=12(3)/2\\x=18$

<em>Find the value of y</em>

substitute the value of x in equation A or equation B

$y=-\frac{1}{3}(18)+6=0$

therefore

The solution is the point (18,0)
